The Preg-Tone Series 6 Model is a safe and accurate ultrasonic pregnancy detector for swine, sheep, alpacas, goats, pygmy goats, llamas, and numerous other mammals over 8 lbs. Very high accuracy at 30-40 days gestation. Preg-Tone comes pre-calibrated for use with swine, but the user can easily recalibrate it for use with other species.
The Preg-Tone uses ultrasound waves to detect amniotic fluid during pregnancy. A short, intermittent tone indicates good contact. When amniotic fluid is detected, the instrument produces a loud, continuous tone. When used on an animal which is not pregnant, the instrument continues to produce the intermittent recurring tone.
